The arrangement of the frame is sli'chthattheintermediate portions l2 and 15 or the meihh rsfleverlep at their endswith the portion 12, above the portion 15 andforr'ning 'the corner ofthe name, the upwardl extending flair' gejll ein'g out awefy eis at l8for the recepsee Figure 3. Theflange'sf l3 and I6 differ in e teht h, anajm'ojuntflequal to the thickness of thelniddle portib'hlZ or [5(lisliall'yof equal thi'ckriess), so that the edge surfaces and 2| willbe in substantially the same plane when the frame; is assembled and theoverlapping re1ation of the frame' rnembersoecurs'. Likewise, theflanges l4 and, differ in extent from their frilddl'e portions l2 and [Bin an amount equal to the thick r i'e s'sot the rr iiddle portions [2 orl5 so that their upper edges 22 end 2 3 will be in te a p e when theframe is as's'mbled' at11d in a p s ion to support the botv torn wall25L of the truck,- as will be readily apparent from Fig. 3.

The bottom wall designated g hereny is provided with downwardlyextendingside flanges 26 and downwardly extendi rfg end flanges 21whibhlalre'fdlded from the stock of the bottom wen- 2'5; Theundersurfacejofthis bottom wall engages the edges 22 and 23 of the,frame mem bers, while its-flanges 2'6 ahd' 21. extend downwardly alongthe downwardly extending flanges I3 and N5 of the frame to the loweredge of the frame and snugly engage therewith. If this truck is made ofstainless steel clad material the'upper surface 28 of the bottom wallwill be the stainless steel coated portion, while the under surface willbe the usual material to which the stainless steel coat is attached.

The side walls of the truck aredesignated generally 30 and the end walls3|. These are sheet stock which are laid against the flanges of thebottom wall snugly engaging therewith and extending from the bottom edgeof the flange of the bottom wall upwardly. Angle iron corner pieces 32are positioned about the corners or junction of the edges of the sideand end walls 30 and 3| and are bolted in place at their lower ends asat 33 on each of two sides which serves to attach the entire assembly offrame, bottom wall, side Walls and corner pieces together. If desired,the edges of the side and end walls at the corners may be additionallysecured by welding. The side and end walls 30 and 3| may have theirinner surfacesf35 of the stainless steel plate and the welding used atthe corners will be of stainless steel material. Thus, the truck may bestainless steel clad throughout its inner surface with no seepage ofrust through the joints of the different parts which come together.

The upper edges 36 and 31 of the side walls 30 and 3| are rolledoutwardly to provide a smooth surface and are suitably connected at thecomers by the insertion of a core which is covered with a weldingmaterial of stainless steel where such structure is used, as at 38 whichwill be more fully described in my co-pending application.

By reason of the flanged bottom Wall and the sides extending below thesurface thereof a pocket is formed beneath the body portion of thetruck. Also, by reason of the framework which I provide for the assemblyof the side walls and the bottom wall, the middle portions, l2 and I5 ofthe members of the frame, will be spaced from the bottom wall 25. Thus,I provide a portion to which the wheel brackets may be secured by boltswithout the bolts protruding into the inside of the body. These wheelbrackets are designated generally 40 and consist of a U-shaped framebolted as at 4| to the middle portion of the Z- shape member of theframework. These U- shaped portions each support awheel as at 42 whichis to rest upon the floor for easy pushing about of the truck. Thesewheel units may be provided in any desired number, I here have shown forillustrative purposes four, one being mounted in the middle of eachframe member. Thus, these units are shown in these four positions as 45,46, 41 and 48.

By the arrangement above specified the truck has a framework upon whichthe wheels are supported. The bottom wall is imperforate and not piercedby the wheel bracket bolts 4|. The edges of the bottom wall are turneddownwardly presenting the stainless steel surface of the flange and sidewall together, thus at the juncture of this bottom wall and the sidewalls there is a long length of material where stainless steel engagesstainless steel, and the junction of the side walls with each otherbeing weldedtogether with stainless steel material prevents any seepageof rust into the body at these points.

' This structure is extremely simple and easy of assemblage. The bottomwall is supported not only from the sides but also from a point spaced asubstantial distance inwardly from the sides so as to support the bottomwall against downward buckling.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.
